Helix is the only family suitable for both breeding and gastronomic purposes (on the markets) all over the world. The snail is a gastropod, cephalopodan mollusc with lungs. The snail is an insufficient hermaphrodite: each fertilized couple lays eggs twice. Both conpling and laying take place generally twice a year in our climate. Theoretically each snail lays from forty to eighty eggs after every conpling.
In practice, the number of snails which can be bred and fattened is by far inferior owing to either a momentary sterility or non-conpling. The period of both grazing and reproduction varies according to climate, height, geographical zones and species observed.
